配置文件，具體字段的含義，可以參考其他文檔。
1.單個文件的配置信息? ?redis_36380.conf
requirepass Paas_2024port 36380tcp-backlog 511timeout 0tcp-keepalive 300daemonize yessupervised nopidfile /data/paas/apps/aicache-redis/redis_36380.pidloglevel noticelogfile "/data/paas/apps/aicache-redis/logs/redis36380.log"databases 16dbfilename dump.rdbdir /data/paas/apps/aicache-redis/dataappendonly noappendfilename "appendonly36380.aof"appendfsync everyseccluster-enabled yes
cluster-config-file nodes36380.conf
cluster-node-timeout 20000
cluster-announce-ip 2409:806a:5af0:2000::f8ac
cluster-announce-port 36380
cluster-announce-bus-port 46380
masterauth Paas_2024這會看配置，才發現，timeout的值設置錯了，想設置成20000的，結果，設置為了0。
?2.其余配置文件
將redis_36380.conf 復制6份，將對應端口都sed修改成對應的端口。
redis_36380.conf? ?-->ip1/?redis_36381.conf
redis_36380.conf? ?--> ip2/redis_36380.conf
redis_36380.conf? ?--> ip2/redis_36381.conf
redis_36380.conf? ?--> ip3/redis_36380.conf
redis_36380.conf? ?--> ip3/redis_36381.conf
3.各個redis都要啟動
?cat start_redis.sh?
cd ?/data/paas/apps/aicache-redis; bin/redis-server redis_36380.conf
echo "36380 start done"cd ?/data/paas/apps/aicache-redis36381; bin/redis-server redis_36381.conf
echo "36381 start done"
4.集群啟動
